All my experience of the world teaches me that in ninety-nine cases out of a hundred, the safe and just side of a question is the generous and merciful side.

Jameson’s aphorism distills a moral rule-of-thumb drawn from lived observation: when faced with a disputed judgment—about a person’s motives, guilt, or deservingness—the position that errs toward generosity and mercy is usually both safer (less likely to commit injustice) and more truly just. The line implies that harshness often rests on incomplete knowledge, pride, or punitive impulse, whereas mercy acknowledges human fallibility and the limits of evidence. It also frames compassion not as sentimental weakness but as practical ethical wisdom: choosing the charitable interpretation reduces the risk of wronging others and aligns justice with humanity.
